LEASE-FORMING DEVICE.

Application filed October 22, 1914.

To all whom it may concern:

Be it known that we, EUGENE HOLT and LAFAYETTE HOLT, citizens. of theUnited States, residing at Burlington, in the county of Alamance andState of North Carolina, have invented certain new and usefulImprovements in Lease-Forming Devices, of which the following is aspecification.

Our invention consists in the novel features hereinafter described withreference to the accompanying drawings, in which we have illustrated oneform in which the invention may be embodied, which has been selected byus for the purpose of illustrating the invention, and the said inventionis fully disclosed in the following description and claims.

Referring to the said drawings,Figure 1 is a side view of our improvedlease former and shield, and designed particularly for taking a lease inthe warp threads prior to placing the same on a loom, a portion of theslasher being shown in dotted lines; Fig. 2 is a top plan view of ourimproved lease former showing only a few of the separating disks andcams; Fig. 3 is a vertical sectional View taken through the lease rodsand clamp forming the end of a beam; Fig. 4: is a similar view showingcords used instead of lease rods and leaving out the clamp; Fig. 5 is aperspective view showing the lease and lease rods; Fig. 6 is a plan viewof the lease, lease rods and clamp as shown on the end of a beam; Fig. 7is a fragmentary view of one of the clamps shown in open position; Fig.8 is a side elevation partly in section of the lease forming roll, theroll being turned out of operative position; Fig. 9 is a similar viewshowing the roll turned into operative position; Fig. 10 is an elevationof one of our im proved lease forming cam disks; Fig. 11 is a verticalsectional view of the same.

In the process of winding yarn from spools or bobbins upon beams for usein looms and otherwise, it is customary to introduce between the warpsat proper intervals what are known as lease rods or cords.

The object of the present invention is to facilitate the separation ofthe warp or to Specification of Letters Patent.

lift one and then the other half of the warp threads for the insertionin succession of the lease rods or cords.

Besides enabling a more perfect and rapid separation and lifting of thestrands, our invention makes it possible for an unskilled person toperform the operation which now under the method in vogue requires fineeyesight and long training.

Our invention relates particularly to an improved lease forming rollused in conjunction with a warp-dressing machine or slasher for forminga lease of the warp threads or yarns after the same has passed throughthe dressing rolls or slasher, so that by the insertion of proper leaseretaining devices, the warp may be severed near the warp beam, leavingthe yarn in two equal separated portions, the threads of which alternateand maintain their crossed relation, whereby when the beam has beentaken to the loom, the yarn in its leased condition may be readily runin through the harnesses.

A further object is to provide a device of this character which willoperate on the finest weaving warps and which may be assembledexpeditiously by an unskilled person. It is to be understood, however,that the device may also be employed as a heddle. and in other relationsin which its use will be advantageous or desirable.

In carrying out our invention, we employ a roll made up of a series ofdisks and cams, which are preferably arranged alternately, and theadjacent cams have flattened or straight portions which are oppositelydisposed and form what we term a lease former, and to combine therewitha shield which will protect the disks and cams and cover the same whennot in use. We also advantageously shape the shield ends in such mannerthat they will act as guides for the lease that they will act as guidesfor the lease rods, when the device is in operation and to enable it toproduce the best effects in connection with the article, with which itis to be used and under the circumstances of use.

In the drawings, 1 designates a portion of the frame of a slasher (shownin dotted lines) in the bearings of which is loosely mounted a shaft 2.A. sleeve 3 envelope said shaft and is provided on its periphery withlongitudinal grooves 4: in which keys 5 rest. In making up our improvedroll the base or support is formed in this way and disks 6 and cams 7are alternately arranged upon said sleeve to form a roll. The disks andcams are provided with notches 8 which engage said keys. It will,therefore, be seen that the turning of the sleeve 3 will simultaneouslymove the disks and cams.

Each cam is provided with a curved face 10 and a flat portion 11 andadjacent cams which are separated by the disks 6 have their flat facesoppositely disposed, whereby the threads Which pass: between said diskswhen the roll is in operative position are separated vertically to forma space for the insertion of a lease rod 12, as shown in Figs. 1, ,3, 5and 6, or for a cord 13 as shown in Fig. 4. After the first lease rod orcord has been inserted, the lease roll (which in its entirety we willdesignate 14) is turned a half revolution to crossthe threads 15vertically and bring the opposite cam faces into action to form the shedfor the second lease rod or cord, and after the second rod or cord hasbeen introduced the roll 14: is again turned a half revolution tocomplete the lease. The ordinary clamp16 is then placed on the warpthreads and the thread is severed, thereby forming the outer extremityof the material upon the beam (not shown). When the extremity of thematerial upon the beam has been prepared in this manner it is ready forthe loom, which forms no part of the present invention.

The lease forming roll is'prefcrably oscillated by' means of a handwheel 17 which is provided upon an extremity of the sleeve 3, whichextends outside of the frame 1 of the slasher. A shield 18 which is inthe form of a half collar with closed ends is preferably clamped uponthe shaft 2 by means of a set screw 19, and entirely incloses overone-half of the roll 14:. Each end of the shield (only one being shown)is provided with a projection 20, which acts to guide the lease rodthrough the shed. By loosening the set screw 19, the shield may beturned on its pivot to the position shown in dotted lines in Fig. 1,whereby the threads will be bridged over and will not engage the leaseroll 14. The shields may be turned by any suitable means (not shown). Itwill also be seen by reference to Fig. 1, that a gravity tensioning roll21, which has spindles 22' that are mounted in the vertical guides 28,is provided between the lease forming roll 14: and the comb 2 1 (shownin dotted lines) which is usually provided upon a slasher for the,purpose of maintaining the threads in proper engagement with the roll14.

From the foregoing it will be seen that we have provided a device fortaking or eration as done by hand. Our device is simple in constructionand easily and practically indestructible. The disks and cams are alsoso arranged and dimensioned that a knot in the warp will pass over andnot break, as the warp is being wound on the beam.

I While we have selected one embodiment of our invention for the purposeof illustrating the same, we do not desire tov be limited to the exactdetails of construction shownand described, as variations therein may bemade without departing from the spirit of our invention.
